How to set time on1440sports watch with onlt three buttons

As your watch has 3 buttons I am assuming that it has the main dial and 2 sub dials maybee to show the date. The centre button should pull out (DO IT GENTLY) and either will stop or click ,you should then rotate it to set the time, when done push it back in to start the watch running.
The 2 outer buttons probably work by pushing them in a click at a time to set there respective dials.

the three dials are for three different time zones, there is no minutes or seconds.
to adjust the middle dial just push the small bottom which is located on the back side of the watch

I have a Sharp SHP5700 and here's how I set the time on that watch. When looking at the watch, there are four buttons. Two on the right side and two on the left side of the watch. By pressing three times on the lower left side button (S2), it places the watch in time setting mode. To change the seconds, minutes, and hours, press on the lower right side button (S4).

What make and model of watch is this?

i dont know how to set the time on my watch .it has three buttons mode ,select and set help

Thank you for contacting FixYa.

Set Digital Watch
1. Press and hold the "Mode" button on the right side of your Arnette digital watch for three seconds to change the watch's mode. Press and hold the "Mode" button repeatedly until flashing digits indicate that you have entered the watch's time-setting screen.
2. Use the top and bottom buttons on the left side of your Arnette digital watch to increase and decrease number values as desired.
3. Press and hold the "Mode" button repeatedly to exit the time-setting screen and return the watch to time-telling mode.
Set Analog Watch
4. Pull out the watch crown on the right side of your Arnette analog watch.
5. Turn the watch crown clockwise to adjust the hands of your Arnette analog watch to the appropriate time.
6. Push the watch crown back in when you are finished setting the time on your Arnette analog watch.

The stop watch buttons don't pull out. There are 2 pushbuttons. The upper one starts and stops the timing function and the lower button resets the timing function. The crown has three positions: 1st position is for winding, 2nd for date setting and 3d for time setting. Once things are set wind the watch in position one and it should run. If it does not take it to a watchmaker. You don't want to fool around with such a valuable watch.
